Its the fact you have to reload it each wash which aint cheap. Not impressed with it to be honest.

 

You dont have to reload it each time. The 1st filter yeh ok only lasts 2-3 washes, but the fill ups last for 10. The shampoo fill up last alot longer to.

Another thumbs up from me, leaves the car perfect, clean n shiny. And its so much faster than using cloths, blades, leathers etc.

 

No probs here either .....works ok for me
